Django 1.6.5中的翻译

Question

最近我一直在做我的前任2到3年前制作的网站（我写这个是因为应用程序很乱，这不是我的错）。老板让我简单地添加英文版多语言。我按照djangoproject文档中的说明，在locale目录中创建了很好的.po和.mo文件，为i18n视图设置了url，并添加了正确选择HTML的表单。问题是，当我从i18n发送带语言代码的POST到setlang视图时，django不会改变语言也不会抛出任何错误。不幸的是，在1.6.5中，django.utils.translation没有LANGUAGE_SESSION_KEY，所以我甚至不知道如何更改会话数据... 所以，在这里你有我的设置：

在urls.py中我刚刚添加：

url(r'^lang/', include(i18n))

我正在使用表单：

<form action="/lang/setlang/" method="post">
  {% csrf_token %}
  <input type="submit" value="{% trans 'Zmień język' %}" />
  <select name="language">
  {% for language in st.languages %}
  <option value="{{ language.code }}"{% if language.code == LANGUAGE_CODE %} selected="selected"{% endif %}>
      {{ language.name_local }} ({{ language.code }})
  </option>
  {% endfor %}
  </select>
</form>

st.languages只是：

'languages': [
    {'code': 'pl',
     'name_local': 'polski'},
    {'code': 'en',
     'name_local': 'english'}]

任何？
